I was making online modification in such CPU when i was in remote program mode starting to edit rungs as per manual
edit rung
modifiy
accept the rung
but i found that after this step the controller fix some output without any change as ex. keep the valve open and not excuting program to close knowing that the block which i was modifing has no relation with this output which is freezed to open
is any one has experience with such situation and why it happened
thanks in advance
